[Collins] Re: [Johnson] Advantages/disadvantages of an "L" tuner circuit?

[Gary Schafer]

You can match almost anything with an L network and it can be a little more efficient than the T network. However the T network is much more versatile. With an L network you will at times have to change it's configuration depending on what you are trying to match. There are about a half dozen configurations of the L network. Series C
on input parallel L on output. Series C parallel L on input. Series L parallel C on output,  etc.
The T network eliminates the need for changing the configuration at the expense of not always being optimum but being able to match a much wider range without making changes to the configuration.

I was considering building a 1KW tuner and if TenTec chooses an L designed, I figured "why not". Can anyone convince me either way? Oh, so that the topic is not off subject: it's for my Collins and Johnson rigs
